Hedge-fund manager William Ackman attempts to prove that the health-food giant Herbalife is really a pyramid scheme after shorting a billion dollars' worth of the company's stock. His quest soon brings him into contact with a group of activists who are organizing a class-action lawsuit against Herbalife, arguing that it preys on low-income Latin-Americans. Directed by Ted Braun (Darfur Now). ~ Jack Rodgers
